Letters Patent No. 93,07 9, dated July 27, 1869.

nnsao'vnn sAsH-HQLDER.

The Schedule referred. to in these Letters Patent and making part of the same.

To all whom it mayconcern:

Be it known that I, LEWIS GIBBS, oi Canton, in the" Figure 3 is a sectional plan of the same, with sash locked down.

Figures 4 are front elevation and planl'oi' the sliding lock-bolt. I i

Figures 5 are front elevation and sectional side view oi' the case.

Figures G are front elevation and sectional side view of the retainingshell.

The nature of my invention consistsn First, in the novel construction of aV device for sup,- porting window-sashes, said device consisting of a circular-formed metallic case, which has within it aretaining-shell, having its hack tbrm'ed to the same curve as that of the inner face of the case, and its fzice formed into such a curve, as that it shall act as a cam around the axis of the case, and against the window-frame, the case and retaining-shell being so constructed, as that the movement of the retaining-shell ini the case is effected by thesliding of the shell within the case, and not by any rolling of said shell on the inner face ofthe case, nor by the rotation of said shell ai-ound an axlepin in the sash-case, as has ,been the practice in previous devices of this class.

The peculiar utility of this mode of construction cosists in the simplicity and ease with which the device can be applied to the sash, the onlytools-required being a bit. oranger, to bore the hole in the sash,.and a hammer .to drive the case into said hele, where it is held without the' aid of screws or any like devices; and the second admiltage being in the extreme lightness and consequent chcapness' of the case lland lshell required, as the case is reinibrced aroundiits entire edge, by its bearing against all parts of the-hole in `the sash in'which it is inserted, while the retaining-shell has a bearing on the whole of its back against the inner face of the ease, when under pressure in sustafin'ng the sash, instead of throwing the whole strain clito anaxle-pn or a light teat, as in previous devices of this class, and' hence has great capacity to resist the.7 strain brought to hear on it. y.

The nature of my invention consists-7 Secondly, 1n the combining with the case and retaining-shell, constructed as described, a sliding bolt, by ineans of. which the retaining-shell is easily manipu lated, and the sash can be securely locked at any desired point in the window-frame, whereby I obtain a very cheap and eiiicient fastening for locking or supporting the sash.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The case B of my fastening is made in lthe circular form shown, with its exterior surface sloping. in the form of a conic UStrum, from the face of the case to its back, ,as shown in side view in ngs. 5.

On the sides of the case are arranged one or more. v sharp Wedge-shaped anges, f f, whichprevent the case from turning in the hole in the sash.

The plate C, which forms the face of the case, is raised above the pla-ne of the body ofthe case, and is of such size as to leave a space, E, Abetween its edge and the lim ofthe case, as shown in gs. 5.

The retaining-shell F is constructed with its back curved to a circle of the same diameter, x, as that'cf the interior ofthe case B, while its faces made-in the general form of an ellipse, as shown in figs. 6, the vsmaller axis of the ellipse being of such length, as that the shell, when setting'squarely in the case, shall have its front face about flush with the open sides of the case, as seen in fig. 3.'

'The shell shown in drawings is made with a raised rim, h, around its face, which falls off to the frame of the shell,`near its back, said back being about onehalf the height of the full shell, and a depression, G, is formed in the shell-frame, in which works the' bolt A.

This bolt A consists of the bolt. proper, a', which is' attened ont and turned up into the arm b, to which is secured the plate c, which' projects outside the case B, and has a'knob, E, attached to it, as shown."

These three parts t together, as shown in iig. 3, the arm b of the bolt A working around in the space E in the case B, and the bolt a-sliding in the depression Gr inthe shell B, while'the flattened rear portion of thebolt c it's between the flangesh h, which are carried along at each side of the depressionG, thus causing the rotary movement of the bolt A` tocommunicate a similar movement to the shell F.

The case B is secured in the sash H, by first boring a hole in said sash ofabout the diameter of the small end of the exterior of the'case, and in such a position as to bring'. the straight and open side' 0f the case B iush with the edge of the sashfH, andthen driving. the case into such hole, where it is firmly retained by its close fit in the hole, due to its wedge-shapedform, and is prevented from turning by the flanges j, which are forced into the wood by the driving of the cas into the sash.

` act as a cam `sqare position in the case B, and the sash lowered,

shown, could be made by making the case B without i E, and by means'of which the shell F could be operated.

The retaining-shell F and bolt Aare placed in the case B before it is driven int-o the sash, and are thus secured in their proper workingjposition.

rIhe raised portion c of the case B is'so arranged as to just fit up to t sash-strip N, as seen in`g. l.

The sash H is supported at Aany point, by drawing down the knob i{,so as to tnrn'tbe shell F out of its square positie in ,the case, thus bringing its lower surface agailist the Window-frame L, and causing it to between said frame and the case B and the sash II, when it is evident that the weight of the sash will act to tighten the cam as it presses' downward, and that the sash will be securely supported,

The sash can be lowered, by'raising it a little, so as to loosen the camfaction of the shell F, when, by means of the knob K, this shell can be held in its as desired.- i

It is evident that the sash could be locked down by drawing up the knob K,and bringing the upper face of the shell F against the frame L; but for greater securityfa hole, n, is bored in the frame L, into which the bolt c is shot by means of the knob K, the bolt being prevented from turning with the shell F in the case B, by a flange, rl, secured on the part c, which slides into a slet/,1), in the plate O, as the bolt is being shot into the lhole n.

It is evident from the foregoing description, that Va cheap form oil Lihstening, construetedon the plan herein the covering-plate C, and with a ange around its edge, to holdthelshell in the case, the bolt A being omitted, and the shell Il being operated, by grasping the flanges l1, 71, at 'the sides of the depression Gr, in a manner readily seen; or the lowering-plate C could be made ush with the edgeslothe case B, and a knob could be cast on the shellll,` which should project through the space The case, retaining-shell, and sliding bolt, can be east of commen castor malleable iron, or of other suitable material, and the face of the case B, as well as they plate C and knob K of the bolt A, may be ornamented as desired.

Having thus fully described my invention, I do not came claim as new the use of a rolling retaining-shell in 'a case inserted in the sash, for the purpose of supporting said sash, when said shell is made in a cylindrical form, and is arranged to roll on the inner face of the case, or is pivoted on an axle-pin in the sashfcase, and is arranged to turn thereon; nor do I claim the use of a sliding lock-bolt in any other sash-fastening than that herein described, as these features havebeen before shown; but V lVhat I do claim as new, and desire to secure by Letters Patent, is

1. The combination of the circular sash-ease B and retaining-shell F, when said retaining-shell is so constructed as that its back shall lit the inner face of the sash-case, and its movement shall be 'effected by itsv instead of rolling therein,

sliding within the sash-ease,

herein or turning on an axle-pin, substantially as is specified. 4

2. The sliding bolt A, when used in combination with'the retaining-shell F, which isfitted to the sashcase B, and slides on the inner face thereof, instead of rolling thereon or turning on an axle-pin, snbstantiall y as and for the purpose herein specied.

'3. The llange d on the sliding bolt A, when nsedin i combination with the slot D in the case B, substantially as and for the purpose specified.

' 4. The case B, provided. with the raised plate C, when used in combination with the retaining-shell I1 and sliding bolt A, substantially as and for the purpose herein specified.

5. The improved sash-supporter and lock herein described, consisting of the ease B, with flanges f and raised plate C, with slot D, retaining-shell F, 'and sliding bolt A, with flange d, the several parts being con strueted, combined, and operating substantially as and for the pinpose specified.

As evidence that I claim the foregoing, I have hereunto set my hand, in the presence of two witnesses, this 27 th day of May, 186).
